Answer 2

Answer:

Tyndall effect is light scattering by particles in a colloid or particles in a fine suspension. So, a true solution does not show Tyndall effect due to scattering of light and scattering is directly proportional to size of sol particles.

Hence, assertion is wrong but reason is correct.
